I don't have any prior experience with MicroLogix so the Communication Toggle Button is new to me. We currently have a few MicroLogix that are using the RS 232 port (Channel 0) to communicate to the HMI. I am needing upload from the PL C to make a slight modification to the program and download it back to the PLC.
The PLC is currently not communicating with me through my Serial to USB converter cable. I have read and found out about the Communication Toggle Button that will allow the PLC to flip back and forth from the User-Defined configuration and default configuration of the communication port. Once I toggle the communication button to default and am able to communicate and upload from the PLC, make my change and insert it back into the PLC, am I able to simply just toggle back the communication button so the PLC will communicate with the HMI as before through whatever protocol it was using before my change? Will it still revert back to the user-defined communication protocol?
